PO: oral • IV: intravenous injection • IM: intramuscular injection • SC: subcutaneous injection • SL: sublingual • TD: transdermal "Strength" is defined as analgesic potency relative to oral morphine. Tolerance, sensitization, cross-tolerance, metabolism, and hyperalgesia may be complex factors in some individuals.
In the Netherlands, morphine is classified as a List 1 drug under the Opium Law. In New Zealand, morphine is classified as a Class B drug under the Misuse of Drugs Act 1975. [153] In the United Kingdom, morphine is listed as a Class A drug under the Misuse of Drugs Act 1971 and a Schedule 2 Controlled Drug under the Misuse of Drugs Regulations ...
Loperamide, sold under the brand name Imodium, among others, [1] is a medication of the opioid receptor agonist class used to decrease the frequency of diarrhea. [5] [4] It is often used for this purpose in irritable bowel syndrome, inflammatory bowel disease, short bowel syndrome, [4] Crohn's disease, and ulcerative colitis. [5]
Rapidly decreasing the dose may result in opioid withdrawal. [7] Generally, use during pregnancy or breastfeeding is not recommended. [11] Hydromorphone is believed to work by activating opioid receptors, mainly in the brain and spinal cord. [7] Hydromorphone 2 mg IV is equivalent to approximately 10 mg morphine IV. [9] Hydromorphone was ...
Extended-release (or slow-release) formulations of morphine are those whose effect last substantially longer than bare morphine, availing for, e.g., one administration per day. Conversion between extended-release and immediate-release (or "regular") morphine is easier than conversion to or from an equianalgesic dose of another opioid with ...

To the contrary, in rats, (+)-morphine acts as an antianalgesic and is approximately 71,000 times more potent as an antianalgesic than (−)-morphine is as an analgesic. [ 1 ] (+)-Morphine derives its antianalgesic effects by being a selective-agonist of the Toll-like receptor 4 (TLR4), which due to not binding to opioid receptors allows it to ...
Drug administration via the nasal cavity yields rapid drug absorption and therapeutic effects. [33] This is because drug absorption through the nasal passages does not go through the gut before entering capillaries situated at tissue cells and then systemic circulation and such absorption route allows transport of drugs into the central nervous ...
